How To Make Potato Gratin Potato Dauphinois Recipe

Preheat the oven to 350°F (175°C).

Grease a baking dish with butter.

Peel and thinly slice the potatoes (about 1/8 inch thick).

In a saucepan, combine the heavy cream, whole milk, minced garlic, salt, black pepper, and nutmeg. Heat over medium until just simmering, then remove from heat.

Layer half of the sliced potatoes in the greased baking dish, overlapping them slightly.

Pour half of the cream mixture over the potatoes, then sprinkle half of the Gruyère cheese on top.

Repeat with the remaining potatoes, cream mixture, and Gruyère cheese. Finish with the grated Parmesan cheese on top.

Cover the dish with aluminum foil and bake for 45 minutes.

Remove the foil and bake for an additional 15-20 minutes, or until the top is golden brown and the potatoes are tender.

Let it cool for a few minutes before serving.
